Add a feature which scatters viewers to small groups for raiding random streamers.
I think this kind of feature would be really interesting and exciting for viewers and streamers. Streamers could press a button to split their viewers to groups of for example 100 people and raid random channels in chosen category or all over twitch. With big streamers getting tens of thousands of viewers, this would mean a lot of small streams would get exposure from this feature. I have noticed chat gets really excited when raids happen, in both the raided and raider channel. This kind of random twist would make it even more exciting and fun!

This would be a ton of fun! Maybe have an option to let the streamer set the list of potential /scatter targets (to do actual team wide raids), I want to know Im sending my community to safe harbors (or at least people I like)
Or even just some tag- or viewer count-based filters for potential landing places. Dont wanna get too crazy up in here
